Sheryl Crow's rehab wish

Sheryl Crow wants to go to rehab because she thinks it will be good for her career.The 46-year-old singer - who has just released her sixth album 'Detours' - is desperate to duet with "hot" Amy Winehouse, who picked up five Grammy Awards last week while being treated for her drugs addiction.Speaking at an intimate show in London, she said: "I want to collaborate with Amy because she's really hot and cool right now."I know one song 'Rehab' was very popular particularly because a lot of young people are in rehab as well. In fact I'm thinking about going. It looks like loads of fun and I know my career will benefit from it."Meanwhile, Sheryl - who adopted nine-month-old son Wyatt last year - has revealed her breast cancer battle in 2006 made her want to become a mother.The star, who split from cyclist Lance Armstrong in February 2006, explained: "I began the adoption process right after I finished my treatment. Wyatt came in May last year. I have always felt like I was meant to be a mom, but I had kept it from happening because I had believed that you are supposed to look for a family with a mom and a dad."
